using namespace std;
class Invoice{
int number;
string description;
int quantity;
 int price;

public:
Invoice(int n,string d,int q,int p);
int getnumber();
void setnumber();
string getdescription();
void setdescription();
int getquantity();
void setquantity();
int getprice();
void setprice();

int getInvoiceAmount();
~Invoice();
};

#include<iostream>
#include<string>
#include"invoice.h"
using namespace std;


Invoice::Invoice(int n,string d,int q,int p){
	number=n;
 description=d;
quantity=q;
 price=p;
}


int Invoice::getnumber(){return number;}
void Invoice::setnumber(){cout<<"\nEnter please the number of item\n";
cin>>number;
}
string Invoice::getdescription(){return description; }
void Invoice::setdescription(){cout<<"\nEnter please the discrepthion of item\n";
cin>>description;
}
int Invoice::getquantity(){return quantity;}
void Invoice::setquantity(){cout<<"\nEnter please the quantity\n";
cin>>quantity;
if(quantity<0)
	quantity=0;
}

int Invoice::getprice(){return price;}
void Invoice::setprice(){cout<<"\nEnter please the price of item\n";
cin>>price;
if(price<0)
	price=0;
}

int Invoice::getInvoiceAmount(){

hmm. Have you tried doing int x = quantity*price; then returning x?

Edit: the function "getInvoiceAmount" is an integer. So after youve returned something. In this case quantity*price; you must "catch" it with an integer in main. Like this -

int invoiceAmountCatcher = obj.getInvoiceAmount(); (I think this is how it is done however I am not certain, try it)

Edit2: Just tested it my example it correct.
